I might be wrong but i believe that Edcomasia is based out of Thailand. Therefore you could ask yourself the question, how qualified are they to speak about positions in China?

As with my previous reply on a different thread to you, i think you need to consider the quality of the information that a recruiter can provide given that all they are doing is passing on what the school has told them. Therefore it's like a big game of Chinese whispers with the risk that by the time the information reaches you it has been corrupted. That doesn't mean that if you go direct to the source that schools won't lie to you (check all the threads on this forum) but that you should at least cross check any information the recruiter tells you with the school itself.
